LUBRICATING DEVICE OF BALL-BEARINGS.

Application filed October 4,

To (4Z6 whom it may concern:

Be it known that I, FRANZ SYMANZIK, a subject of the King of Prussia", residing at No. 1 Kesslergasse, Sehweinfurt, in Germany, have invented new and useful Improvements in Lubricating Devices of Ball- Bearings, of which the following is a specification.

This invention relates toa device for the perfect and continuous lubrication of ball bearings and the like by circulation f the lubricating fluid or medium.

The ob ect oi the invention is to so ar- H range the bearing and its accessory parts-- that the row or rows of balls are separated from the oil chamber and to avail of the centrifugal force for driving theoil away from the rotating parts, while fresh oil will permanently be reconducted upon theopcrating parts to be lubricated.

To attain this object, the casing of the hall thrust bearing is provided with passages which unite the space encircling the ball series, with the space arranged between K the ball series and the shaft or axle, through which passages the oil can be admitted again to the balls inside the row. Furthermore the lower part of the said outer space which is the oil reservoir is separated from the ball series by a plate or partition.

' Another object of the invention is to so arrange the elements of the bez tring that the said partition may easily be applied to a ball thrust bearing and removed therefrom at will for cleaning or other-purposes, however effectively separating the ball series from the oil chamber, so that the balls will not be plunged but only constantly moistened by the circulating lubricant.

Further-objects of the invention ill be Specificationof Letters Patent.

shaft 5 by any suitable means, two bearing disks or plates 9 and which are stationarily mounted in a box or casing 20, and two series of balls 7 and 8 held between the rotating disk (3 and the stationary disks 9 and 10, respectively, and rolling on concentric paths forn'ied in the opposite faces of. the said disks 6, 7 and 8, which paths have the usual concave shape. Preferably the balls of the single rows are spaced from one another by a spacer-{or retainerring of any well known construction, for example, as shown and numbered 7 and 8*, respectively in the drawing.

The rings 9 and 10 are supported and coaxially held in the casi1fg20 through rings 13 and 14, respectively, by means of en-v gaging flanges or the like. Bores or channels 12 provided in the said supporting rings 13 and 14k and distributed throughout or partly around their circumferences are made to connect or provide passages connecting the chamber or space 21 formed betweeii the wall of the casing and the periphery of the ball bearing, With the space or clearance 252 left betweenthe shaft 5 or a part mounted thereon and the inner. side of the series of balls 7 and S and race-rings 9 and 10. Said channels preferably possess radial direction. It may easily be understood that grooves cut in the rings or in the casing, or any other passages will have the same effect. i

The separation of the ball bearing from the lower part of the chamber 21 which forms the receptacle 18 for the lubricant,

as the oily there collects by gravity, i obrings 13 and 14, but its dimension may vary according to the level of the lubricant contained in the oil chamber 18; it being only required that its upwardly directed extremities prevent th e,o.vcrfiow of the oil from the chamber [8 lo the upper face oi said plate. Any convenient means may be used to 'liX the said plate in it position rigidly' or removalily. For example,'a pin 17 attachcd to the late and aided in a bore of the casing with its free extremity can secure the plate against displacement, while a coiled spring 16 presses'the plate 15 on the peripheries of the rings 13 ahcl ll, so that a space 19 is formed above the plate 15 and between said rings which spacei is separated from the lubricant.

In the drawing two series of balls are shown whichare operative in opposite d1- rections, however, also be used with shaft is only tion.

The operation of the lubricating device is as follows: 7 V l At the beginningof the rotation of the shaft the oil which at rest had collected in the space 19, will be thrown out in the direction of the arrows in Fig. 2 by the impulse received from the revolving disk 6, ballrows and their retainer rings, whereby it is supthe lubricating device can one row of balls, if the posed that said parts rotate clockwise. The

oil sported upon the wall of the casing :20 then passes down into the chamber 18, causing the rise of the level of the therein. Owihg'to the open communication )rescnted bvthe passages 12, the oil will conlinuously flow from the receptacle 18 into the space 22, as indicated by the arrows, and be distributed to the series of balls 7 and 8 at their inner side, whereafter it is driven thercthrongh by the centrifugal torceand then thrown out of the chamber 19, as dis closed heretofore.

and consequent heating oi the lubricant will greatly be reduced.

In the drawing a constructional embodiment of the invention has been represented for purpose of example, while in the foregoing specification several modifications have been mentioned. This will makeit clear that the lubricating device can he performed in difierent ways.

What I, therefore, broadly claim as my invention, is

1. in a device for lubrication, the combination with a thrust ball bear ng, of a casing having an oil chamber external to the periphery of the said ball bearipg, and passages connecting said chamber with the inner side of said hearing, a receptacle for to be supported in one dircc oil contained While a continuous circulationof the lubricant 1S established which eddying the lubricant located below the ball bearing, and a partition adapted to separate the ball hearing from. the said receptacle. 9

2. The combination with a thrust ball bearing, of a receptacle for thclubricant arranged below, and partly encircling, the said ball bearing, the periphery of the ball hearing being separated fronrthe said receptacle, while the inner side of the ball bearing is in open conmnmication with the receptacle through passages.

3. The combination with a thrust ball bearing. of a receptacle for the lubricant located below. and partly encircling the said ball bearing, and a partition adapted to sep urate the peripherv of the ball hearing from said receptacle. the inner side oi the ball bearing being in open communication with the said receptacle.

l. The combination with a thrust ball bearing. of a casing therefor which forms a receptacle for the lubricant, said receptacle partly encircling the ball barring, a partition adapted to separate the periphery of the ball hearing, from the receptacle, and a number ofrings supporting the hall hearing and said partition and being provided with passages establishing communication between the receptacle and the inner side-oi the ball bearing.

The combination with a thrust ball bearing, of a receptacle; for the lubricant, which receptacle partlyencircles the said ball beari ng,'a partition adapted to separate the periphery of the ball hearing from the said receptacle, and uu-ans capahe or removably fixing the said partition between the ball bearing and the rcceptaclmthc inner side of the ball-bearing being" in open communication with the receptacle.

6. The combination with a thrust ball bearing". of. a receptaclc for thclubricant, which receptacle partly encircles the said ball. bearing, :rpartition located between, and adapted to separate the periphery of the ball bearing from said receptacle. and passages adapted to comnumicatc the inner side of the ball bearingv with the receptacle.
